Definitions

  • the present invention relates to an orthodontic implant structure that is embedded in bone in the mouth to form a fixed base for performing straightening that causes teeth to move.
  • an orthodontic treatment is performed that consists of embedding a screw-type implant body that forms for example a cylindrical thread portion in the bone of the jaw portion, having this serve as a fixed base, fixing a plate or wire to this implant body with a fixing means (brazing or the like), and fixing the end portion of the plate or wire to a tooth (for example, refer to Patent Document 1).
  • Patent Document 1 discloses an implant structure that fixes an anchor head that provides a slot at the head portion of the implant body, with a screw hole that passes through this anchor head in the vertical direction being provided.
  • the implant body is fixed by being embedded in a jaw bone, a wire having one end fixed to a tooth is engaged in the slot, and by screwing a screw into the screw hole, the wire is fixed at the distal end portion of the screw.
  • a screw-type implant has a bolt shape with a thread formed on an implant body as disclosed in Patent Document 1 mentioned above, and forms an anchor by screwing the thread portion into bone under a membrane.
  • a three-point fixing type implant has a structure that is provided with a projecting portion (support portion) that projects out in a direction that is orthogonal to the axial line direction at the distal end portion of the implant.
  • Patent Document 1 Japanese Unexamined Patent Application, Publication No. 2004-57729
  • US 2004/0147931 discloses an orthodontic implant structure comprising a base plate having a plurality of holes through which the threaded portions of fixing screws can extend, but their engaging portions (screw heads) cannot.
  • the implant structure is thereby fixed to the bone of a person's upper or lower jaw.
  • a screw-type implant can be readily fixed by rotating a screw without the need for performing a surgical operation.
  • the screwed state is inadequate, and during straightening of teeth, when a force acts in the direction of the screw loosening, there is the possibility of the screw loosening, the stability worsening, leading its inability to be used as a fixed base.
  • the three-point fixing implant has a structure that is comparatively harder to come out compared to the screw-type implant, it requires a surgical operation to embed the projecting portion, and has the possibility of taking time for the embedding work.
  • the upper structure body such as a plate or wire is directly fixed to the implant, when performing straightening by exchanging the upper structure body with an upper structure body having a different shape, the implant that has once been embedded must be extracted, and then the new implant must be embedded. Accordingly, there is the possibility of not being able to easily change the upper structure body.
  • the present invention has as its object to provide an orthodontic implant structure that can be easily embedded without requiring a surgical operation, and that can be firmly fixed with no looseness.
  • the present invention has as the other object to provided an orthodontic implant structure that can cause the upper structure body to be removable without extracting its implant.
  • the first aspect of the orthodontic implant structure in accordance with the present invention is an orthodontic implant structure including: an upper structure body having an insertion hole; a pair of bolts of which each bolt has a head thread portion at one end side in the lengthwise axial direction, a locking portion, an engaging portion, and an embedding thread portion at the other end side in the lengthwise axial direction in this order; a base plate that has a projecting thread portion over which the insertion hole can be fitted and a plurality of locking holes, with each of the locking holes capable of allowing insertion of the head thread portion and the locking portion of each bolt but not capable of allowing insertion of the engaging portion, so that by locking with the locking portion is capable of blocking rotation of the locking portion about the lengthwise axial line; first screwing members that can be screwed onto the head thread portions; and a second screwing member that can be screwed onto the projecting thread portion, wherein the locking portions of the pair of bolts to be embedded in the jaw and the locking holes of the
  • the base plate is disposed by locking the locking holes of the base plate on the locking portions of the pair of bolts that have been embedded, and by screwing the first screwing members onto the head thread portions of both bolts, fitting the insertion hole of the upper body structure over the projecting thread portion of the base plate, and screwing the second screwing member onto the projecting thread portion, the upper structure body can be fixed in the mouth. Since the locking portions of the pair of bolts, by having a predetermined shape, are made to lock in the locking holes of the base plate, rotation of the pair of bolts with respect to the base plate is restricted, whereby they are firmly fixed without coming loose.
  • the upper structure body can be attached and detached from the base plate by removing the second screwing member, when for example it is desired to move a tooth by pulling it in a different direction, it is possible to perform straightening of teeth by exchanging the upper structure with an upper structure body that has a different shape. Also, by providing the engaging portion at the upper portion of the embedding thread portion of the bolt, it is possible to prevent the head portion of the bolt from sinking into the membrane.
  • the cross section of the locking portion that is perpendicular to the lengthwise axial direction has a polygonal shape.
  • the engaging portion has a cross section of a size that can encompass the circumscribed circle of the polygonal shape of the locking portion.
  • At least one locking hole has a hole cross-sectional shape that is complementary to the polygonal shape of the locking portion.
  • At least one locking hole has an elongated hole shape that extends in the direction approximately perpendicular to the lengthwise axial line direction. In this case, it is possible to lock the locking portion of one bolt in the locking hole of the base plate which is not the elongated hole, and lock the locking portion of the other bolt within the range of the elongated hole (locking hole) of the other bolt.
  • the orthodontic implant structure of the present invention it is possible to restrict rotation of the bolts by causing the locking holes of the base plate to lock with the locking portions of the pair of bolts, the bolts do not slip out and loosen, and it is possible to firmly fix the bolts to a bone in the mouth. Since the implanted bolts do not wobble, it is possible to prevent the first screwing members that are screwed onto the head thread portion from loosening. Moreover, by being an implant structure that does not require a surgical operation, the bolts can be readily embedded simply by screwing in with rotation.
  • this implant structure it is possible to exchange only the upper structure body without removing the bolts that have once been embedded. Accordingly, it is possible to exchange the upper structure body with a suitable upper structure body depending on the teeth straightening method such as changing the direction of pulling the teeth, and so it becomes possible to move teeth in various directions with respect to the teeth being straightened, and suitable and reliable treatment can be performed.
